The computer’s brain is considered to be the central processing unit or CPU for many people, but the analogy is not inaccurate, because the human brain can do so much more than the CPU. The...

Computer Forensics Fields - A Brief Overview

The computer forensics field, has helped the justice department lock up a lot of offenders, and as technology advances criminals, find it very hard to hide or delete incriminating data from a...

Data Compression is a Great Way to Reduce Data Size

The process which reduces data sizes, by removing excessive information is known as data compression. The size of a file is reduced, in order to save space, save time and reduce redundancy, during...

Radio Frequency Technology one Aspect of Mobile Technology

radio frequency

The world of computers, changes every day, and as technology students, one must learn to stay current, with the skills, we would say we have acquired throughout our working experience.

It’s important, that we learn all technology, not just one aspect of it, or else you can be fired from your job, and not be able to make a living for yourselves.

As a technology student, you need to be a well-rounded programmer, computer scientist or a computer engineer, and you need to know how to do, more than one thing at a time.

Don’t just rely, on one aspect of your skill, and think, that you will be able to move through the technology arena, without a problem.

In today’s article, we are going to talk about, one aspect of mobile technology, so that we may understand better, how it has really changed, the lives, of many people.

The mobile technology, has had a profound change in the way, which we communicate with each other, and a profound change, in the way that we consume information and the news.

As you would already have guessed it, many of us, use the Internet and social media to communicate with families and friends, then turn around, and expect to receive the same type of treatment, when we see each other again, face to face.

Face to face communication, is very important, but many people don’t care to meet face to face, instead they rather use the internet to communicate with other people.

Mobile phones today, are referred to as smartphones, because they offer many computing capabilities.

John F.

Mitchell and Martin Cooper from Motorola demonstrated the first mobile phone.

As a portable device, which is able to make and receive calls, over a radio frequency link, is one of the most rapidly used device in the twenty first century.

The radio frequency (RD) technology, is part of the mobile device technology, known as wireless; it is an electromagnetic wave frequency, which lies in the range, extending from around 3 kHz to 300 GHz, and it includes those frequencies used for communications or radar signals.

RF itself, has become synonymous with wireless technology, because it describes, high frequency signals, such as 1605 kHz and computer local area network, we all know as LAN.

There are three major categories, which RF measurement methodology, can generally be divided into.

The three major categories, of the RF measurement methodologies, are: spectra analysis, vector analysis, and network analysis.

The most popular type of RF instrument, in many general-purpose applications, is the spectrum analyzers; they also provide, basic measurement capabilities.

The spectrum analyzer is very popular, because the user can view, power-vs-frequency information.

Sometimes the analog format are demodulated by the spectrum analyzer, and can be formatted to amplitude modulation also known as AM, frequency modulation, better known as FM and phase modulation also known as PM.

Vectors or real time signal analyzers and generators, are all vector instruments.

Time, frequency, phase, and power information from signals of interest, are all captured by vector instruments, which also analyze and generate broadband waveforms.

Spectrum analyzers are weaker than vector instrumentation, because vector instruments, offer excellent modulation control, and signal analysis.

S-parameter measurements and other characterization measurements, on RF or high-frequency components, are don’t using the network analyzers.
